There’s a new image format on the browser block and it’s very performant indeed. Jake has all the details you didn’t ask for.
How and when did I get to the point where I would consider a page weight of 4 MB on a large page and 500 KB on a small page normal?
This isn’t just a well-earned rant from Manuel. I mean, it *is that, but it’s also packed with practical performance advice.
When it comes to frameworks and UI libraries, there are some interesting numbers. Given the volume of chatter in the dev world, you’d be forgiven for thinking that React is used on the majority of websites today. The real number? 4.6% of websites. That’s less than the number of websites using CSS custom properties.
This is reminding me of what I wrote about dev perception.
Worlds of scarcity are made out of things. Worlds of abundance are made out of dependencies. That’s the software playbook: find a system made of costly, redundant objects; and rearrange it into a fast, frictionless system made of logical dependencies. The delta in performance is irresistible, and dependencies are a compelling building block: they seem like just a piece of logic, with no cost and no friction. But they absolutely have a cost: the cost is complexity, outsourced agency, and brittleness. The cost of ownership is up front and visible; the cost of access is back-dated and hidden.
This looks like a nice way to get a blog up and running:
Blot turns a folder into a blog. Drag-and-drop ﬁles inside to publish. Images, text ﬁles, Word Documents, Markdown and more become blog posts automatically.
Jason describes the next big thing in web typography: streaming fonts!
…to enable the ability for only the required part of the font be downloaded on any given page, and for subsequent requests for that font to dynamically ‘patch’ the original download with additional sets of glyphs as required on successive page views—even if they occur on separate sites.
This is my kind of URL nerdery. Remy ponders all the permutations of URLs ending with slashes, ending without slashes, ending with with a file extension…
This’ll be handy the next time I want to send someone a file: drop it in here, and then paste the link into a DM/chat.
Following on from that proposal for a browser feature that I linked to yesterday, Tim thinks through all the permutations and possibilities of user agents allowing users to throttle resources:
If a limit does get enforced (it’s important to remember this is still a big if right now), as long as it’s handled with care I can see it being an excellent thing for the web that prioritizes users, while still giving developers the ability to take control of the situation themselves.
A short text file, imbued with meaning and memory.
A handy in-browser image compression tool. Drag, drop, tweak, and export.
‘Sfunny, this exact use-case (styling a profile component) came up on a project recently and I figured that CSS grid would be the right tool for the job.
I started writing for myself. The writing was helpful for me and luckily it was helpful for other people as well. But even if you’re the only one that reads your blog it is still helpful as a way to learn.
This seventeen year old profile of Tim Berners-Lee is fascinating to read from today’s perspective.
I remember Jason telling me about this weird service worker caching behaviour a little while back. This piece is a great bit of sleuthing in tracking down the root causes of this strange issue, followed up with a sensible solution.
New Privacy Rules Could Make This Woman One of Tech’s Most Important Regulators - The New York Times
It’s kind of surreal to see a profile in the New York Times of my sister-in-law. Then again, she is Ireland’s data protection commissioner, and what with Facebook, Twitter, and Google all being based in Ireland, and with GDPR looming, her work is more important than ever.
By the way, this article has 26 tracking scripts. I don’t recall providing consent for any of them.
A profile of Susan Kare, icon designer extraordinaire.
I loved the puzzle-like nature of working in sixteen-by-sixteen and thirty-two-by-thirty-two pixel icon grids, and the marriage of craft and metaphor.
